gnutls_aead_cipher_decrypt(3) gnutls gnutls_aead_cipher_decrypt(3) NAME gnutls_aead_cipher_decrypt - API function SYNOPSIS #include <gnutls/crypto.h> int gnutls_aead_cipher_decrypt(gnutls_aead_cipher_hd_t handle, const void * nonce, size_t nonce_len, const void * auth, size_t auth_len, size_t tag_size, const void * ctext, size_t ctext_len, void * ptext, size_t * ptext_len); ARGUMENTS gnutls_aead_cipher_hd_t handle is a gnutls_aead_cipher_hd_t type. const void * nonce the nonce to set size_t nonce_len The length of the nonce const void * auth additional data to be authenticated size_t auth_len The length of the data size_t tag_size The size of the tag to use (use zero for the default) const void * ctext the data to decrypt (including the authentication tag) size_t ctext_len the length of data to decrypt (includes tag size) void * ptextthe decrypted data size_t * ptext_len the length of decrypted data (initially must hold the maximum available size) DESCRIPTION This function will decrypt the given data using the algorithm specified by the context. This function must be provided the complete data to be de- crypted, including the authentication tag. On several AEAD ciphers, the au- thentication tag is appended to the ciphertext, though this is not a gen- eral rule. This function will fail if the tag verification fails. RETURNS Zero or a negative error code on verification failure or other error. SINCE 3.4.0 REPORTING BUGS Report bugs to <bugs@gnutls.org>.
